I get to travel a fair bit yet every time I fly over London I believe I am coming home to the best city in the world. It has everything from amazing architecture, green spaces and wonderful parks , an exceptional array of great restaurants. Friendly people all over. Great shopping. History everywhere you look. I don't think it is any more expensive these days than other major cities but it is true that the more money you have the more opportunities open up. Whatever you want or need can be found.
